ALARM-WATCH.

Speciication of Letters Patent.

Patented Mar. 4, 1919.

Application led November 21, 1917. Serial No. 203,174.

To all whom 'it may concern.'

Be it known that I, CHRISTIAN EDMUND- soN, a citizen of the UnitedStates, residing at Tientsin, China, have invented certain new anduseful Improvements in Alarm- Watches, of which the following is aspecification.

This invention is an alarm watch and has for its principal object theproduction of a device which will sound a signal at a desired hour.

Another object of this invention is the production of anV alarm watchwherein one of the hands will close a circuit at a desired hour forautomatically sounding a signal.

Another object of this invention is the production of an alarm watchwhich has a plurality of insulated sockets carrying circuit terminals,while a plug is also provided having fingers to fit within the socketsfor allowing a circuit to be formed at apredetermined hour, according tothe sockets in which lthe fingers are inserted. Y

With these and other objects in view, this invention consists of certainnovel combina-k tions, constructions, and arrangements of parts as willbe hereafter fully described and claimed.

One practical form of construction and assembly will be described andillustrated Y in the accompanying drawing in which- Figure 1 is top planview of the alarm watch as constructed in accordance with the presentembodiment,

Fig. 2 is a fragmentary side elevation of the alarm watch, portions ofthe retaining strap being shown in section, and n 3 is a diagrammaticview of the wirino system of the present invention.

" lliteferring to the accompanying drawing by numerals, it will be seenthat 1 indicates the watch casing, which may be provided with anysuitable operating mechanism for driving the hands 2 and 2. Frames 8 areformed on the casing 1 in diametrically opposite positions, as shown inFig. 1. The retaining strap 4 is passed through the frames 3 and bearsupon the casing 1 as illustrated in Fig. 2. It is of course obvious,that this strap 4 may be provided with a buckle 5 at one end toreceivethe opposite end 6 of the strap, whereby the watch may be retained uponthe wrist of the wearer.

The contact posts 7 are arranged in pairs upon the dial of the watch,wherever it is desired or any hour or fraction of an hour asisllustrated in Fig. 1. The contact posts 7 have wires 8 extendingtherefrom and connected to the sockets 9, which sockets may be suitablyinsulated from the casing 1, if so desired, as is shown in Fig. 1. Thesesockets 9 are arranged in pairs and spaced relation upon the peripheralside of the watch, as shown in Fig. 2.

1t is of course obvious that any suitable form of a signal may beemployed in connection with the present invention although a pair ofbells 10 are mounted upon the strap 4 and these bells are obviously ofthe usualmagnet type of an electric bell as is clearly shown in Figs. 1and 2.

` connected to one pole of the bell. as shown at l13. The conductor 14leads from the same pole and is connected to the pole 15 of theremaining bell. The conductor 16 leads from the remaining pole of thelast mentioned bell and is connected to the pole 17 of the firstmentioned bell. A conductor 18 leads from pole 17 and is connected tothe linger 19 carried by the plug body 20. This plug body 20 is ofcourse formed of suitable insulating material, as is clearly shown inFig. 3. f The plug body 20 is also provided with a second finger 19projecting therebeyond as the finger 19. The conductor 21 leads from thelinger 19 and is connected to p forth it is obvious that the watch maybe retained upon the wrist of the wearer in the usual manner. If it isdesired to have the signal sounded at a certain hour, for in- 5 stanceas at 5 oclock, the plug body 2O is moved to the necessary point forpermitting the projecting ends of lingers 19 and 19 to be passed intothe sockets 9 corresponding to the hour the signal is to be sounded.Thus 10 it will be seen that the fingers 19 and 19 will be connected bythe conductors 8 to the contact posts 7. When the hour hand finallyengages the contact posts 7 it will close the circuit, thus causing thecurrent to pass from the source of supply 11 over conductor 12 to thepole 13. A portion of the current will also pass over the conductor 14through the bell 15 and return over conductor 16 to the pole 19.Therefore, the two bells will simultaneously ring. The current will passfrom pole 17 over conductor 18 through finger 19 and the Wires 8, aswell as the hour hand 2. The current returns through finger 19 andconductor 21 to the source of supply 11, thus causing the bells to ringas long as the hour hand remains in engagement with the posts 7, at thehour the alarm is sounded, or until the plug has been removed from theselected sockets, which of course will break the circuit.

In order to change the hour when the signal is to be sounded, it is onlynecessary to withdraw the fingers from the sockets by the removal of theplug 2O from engagement with the periphery of the casing 1. The cables18 and 21 are of sufiicient length to permit the plug to be moved at anyplace desired from the periphery of the casing` as it is necessary toperform this function in order to allow the signal to be sounded atdifferent hours. By moving the plug around the periphery of the casingthe fingers may be inserted in selected sockets in a manner similar towhich they are inserted in the sockets adjacent the hour 5, as shown inFig. 1.

From the foregoing description it will be seen that a very efficientalarm watch has been provided since the watch may be strapped upon thewrist of the wearer without interference from the alarm attachmenttherefor. The signal may be changed so as to be sounded at a desiredhour, as has been hereinbefore described, and at the time desired, thecircuit will be closed by the engagement of the hour hand with selectedcontact posts thus causing the bell to ring until the hour againdisengages the contact posts. It is of course obvious that many detailchanges may be made in the construction of the present invention Withoutdeparting from the. spirit of the device, such for instance as placingthe sockets upon the dial rather than upon the periphery of the casingas shown and for this rea-son it is not intended to limit theconstruction of the present invention to the specific form herein shownbut to include all such forms of the alarm watch properly coming withinthe scope of the device as claimed.

What I claim is 1. In a device of the class described, the combinationof a watch having alined frames formed on its periphery, a retainingstrap extending across the back of the Watch and extending through saidframes, said strap having a longitudinal passage extending therethroughintermediate its ends, bells fixed upon said strap, adjacent theframes,conductors connected to said bells and extending through said passage,thus providing an even wearing surface upon the outer surfaces of thestrap, and means for closing the circuit over said conductors at apredetermined hour for ringing said bells.

2. In a device of the character described, the combination of a watch,including hands, wires carried by said Watch, contact posts connected tosaid Wires in the path of movement of one of the hands, socketsconnected to the remaining ends of said Wires, signal means carriedadjacent said watch and means removably fitting within selected socketsfor closing a circuit at a predetermined hour, when one hand engagescertain of the contact posts.

3. In a device of the character described, the combination of a watchhaving Wires connected to contact posts, said Watch having hands, saidposts being in the path of movement of one of said hands, socketsconnected to said wires, bells connected to said watch, conductorsconnected to said bells and including a source of energy, a removableplug consisting of a body having independent iingers extendingtherebeyond, said fingers also being connected -to said conductors,whereby the projecting ends of said fingers may be removably carriedwithin selected sockets, thus causing a circuit to be closed at apredetermined hour when one of said hands engages the binding postscorresponding to the sockets carrying the fingers of said removableplug.

1. In a device of the class described, the 115 combination of a watch, aretaining strap extending across the back 0f said Watch, and means forholding said strap in engagement with said watch, said strap having alongitudinal passage extending therethrough intermediate its ends, bellsfixed upon said strap adjacent said watch, conductors connected to Saidbells and extending through said passage, thus providing an even Wearingsurface upon the outer surfaces of Said strap, and means for closing acircuit over said conductors for ringing said bells.
